HELP.....odd discharge! Any Doctors or nurses on here?

Ok first....I cannot go to the Dr right now so I am just looking for someone who may have experienced this and could tell me what their outcome was or if you're a Dr or nurse and could give me any input until I can get to the Dr. I've been having an increase in vaginal discharge for the last few weeks, when I wipe its a pale yellow color and on my panty liner it's yellow and dries a little darker and almost looks yellow/green when it dries. When I sit on the toilet I do smell an odor that isn't normal for me, but it doesn't exactly smell very fishy...it's almost like a sour vinegar smell. There's no pain and no itching and I've only been with the same partner for over 5 years. I know there's something going on and it's not normal...does ANYone have any suggestions or experiences with this? Thank you so much!
